All sellers making retail sales of taxable goods or services in Nebraska are required to register with the state and collect and remit sales tax. As Nebraska is a Streamlined Sales Tax state, out-of-state businesses without a sales tax obligation are encouraged to register for sales tax purposes.
Since the kinetic energy increases with the square of the speed, an object doubling its speed has four times as much kinetic energy. For example, a car traveling twice as fast as another requires four times as much distance to stop, assuming a constant braking force.
Thus, the work done on any object goes into changing the kinetic energy of that object. As an example, we can calculate the power of a 1000 kg sports car that can accelerate from 0 to 100 km/hr in 10 seconds. In order to be able to get our answer directly in Joules we first convert the speed to m/s.
